BEATER.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed January 18, 1915. Serial No. 2,938.

To all whom it may concern:

Be it known that I, LAVERN vBolmwnnn, a citizen of the United States, residin at New York cit in the county of New and State of ew York, have invented certain new and useful Improvements in Beaters, of which the following is: a specification, reference being had therein to the accompanying drawing.

improved manner of constructing the beater-- frame upon which are mounted actuating means and beater-blades so that all parts of the frame will be rigid and thereby insure a true alinement of the beater-blades and actuating means whereby these parts will operate to the best advantage.

Heretofore beaters have been made ,very similar to the present device, but they have all been open to the followingfdefects:

First: When made of simple construction J the were not durable.

ing and twisting of the framework and econd: The framework when under the stress of the operation of beater-blades and operating mechanism would bend and twist so that these mechanisms would be thrown out of alinement and the perfect operation of the beater materially hampered.

Third: In very large beaters where the framework was of greater-size even greater difiiculties were encountered both as to bendalso in the disarrangement of the actuating mechanism in relation to the beater-blades which are driven thereby. I

Applicants invention thoughf'o'f simple construction, and though cheap to-manufacture overcomes the above .noted" difiiculties. 4

Further objects and advantagespf the present improvement will ,befset kforth in the following .descriptio'ni 'g and appended drawings in which,1'? a 1 e 3 Figure 1 is a side elevation ofmy improved beater showing beater-blades and an actuating means mounted upon my improved framework,

support upon which the beater-blades are mounted.

F 1g. 4 is aperspective view of a modified form of beater framework showing the beater-blades actuating means and handle I removed therefrom. 1 I F1g. 5; 1s a detail enlarged perspective view of the clamp used in connection with the modified form .shown in Fig. 2.

parts, 1 represents the beater framework carrymg at its upper end a handle 2, and at its lower end a substantially U-shaped portion conslsting of two vertical walls3 and 1 and one horizontal wall5. At the point 6 on the beater-frame an actuating .gear wheel 7 is pivoted, and this gear wheel is rotated by means of a crank 8 and handle 9.

Attention is called to the fact that the substantially U-shaped portion of the frame is points 10 and 11 and right at the junction of the vertical walls '3 and 4: and the horizontal wall 5. These .ri ht angles are formed in the frame for t e purpose of giving rigidity and strength to it to take up and'compensate for the strains 3 which are put upon this frame during theoperation of the actuating being between the two portions 12. The

other vertical wall 4 is similarly provided with two outwardly struck portions 14 and one inwardly struck portion 15. In addition, however, the upper edge of the vertical wall and integral with the upper struck out portion 14 is provided a horizontall extend- 1ng'lip-19 providing a stop forthe upper end of the beater supporting wire herein- I hese struck out portions are for the urpose of receiving the upper ends of a su antially U-shaped supporting wire 16 upon which beater blades 17 are mounted, carrying at their upper ends and adjacent the lower edge of the vertical members 3 and 4 gear-wheels 18 which mesh with the actuating gear 7. The upper pore tion of the two ends of the wire su port 16. are flattened so as to be of rectangu ar cross;

{'21 adjacent its junction with the ends of'the supporting wire 16. This clamp firmly locks section as shown at the point 20. It is to be understood however, that these wires may be flattened to present any number of' sides without departing from the spirit andscope of the present improvement; This portion 20 is of a length equal to i the combined lengths of the struck out portions carriedby the vertical portions 3 and 4. Due to the shape ofthese wires when they'are once inserted between the struckout portions, they or rotated in the struck out portions 2 as would bethe case were they of circular cross sectionas is'the remainder of the supporting wire 16. No-specific claim is made herein Particular attention, however, is called to which is of substantially a U-shape, the up-..

the specific manner of arranging the struck;

out portions upon the vertical walls 3 and i. Due to the arrangement of these struckout portions as shown,

when the heater is made of a greater size to facilitate its use in hotels, bakeries, etc., the

construction of the beater'blades support 'ing wires is different, and the description of this modification will now be. taken up.

Referring to Fig. 4, it will be seen-that. the lower U-shaped portion of the beater framework is of substantially the same. construction as shown in Fig. 1, and the assembling of the upper ends of the U-shaped supporting wire with the struck out portions is also identical with that shown in Fig. 1. In this modified form of beater, however, an additional supporting wire 21 is provided per ends 22 thereof bein fastened within the horizontal portion 5 o the beater frame.

work ina s eclfic manner hereinafter to be described. e supporting wire 16, unlike its construction in Fig. 1, is deeply notched atthe point 25 forming a seat for the auxiliary supporting wire 21. Extending ends 23 and 24 are-formedon each side'of the notch 25. At the point 26-the auxiliary support: ing wire 21 is flattened on its top and bottom forthe purpose of assisting in receiving a clamp'27, which is'of the shape of across,

the legs of the cross being of sufiicient shape will beheld rigidly and can not'be twisted I the upper ends of the supportingv framework wire 17 are securely, clamped and when this. wire'is put under the stress of the rotating beater-blades,- it cannot be'bent or twisted sidewise but will remain perfectly rigid and. will insure at all times a perfect 'alinementof the small gears. 18 with the large actuating gear7 to be bentin their centers and thence up andaround the two ends 24 of the supporting wire l'6andalso'around the supporting wire these two wires together and at. the same time also'clanips" the ends 23 and 24 of the supporting wire 16,; togethen Due-to the' deep notch in the beaterblade supporting .wire 16is deeply notched asbefore described. i The specific mannerof attachingthe upper ends 22 ofthe auxiliarysupporting wire 21 consists in first cuttinga V-shapednotch 28 in the periphery of the wire and then passing the wire through a'hole 29 formed in the horiaontalfsurface 5 of the-framework.

'Aften thepends 221'are in position in the holes'29, they are struck with; a tool at the point 30 and the metal of the horizontal por tion 5 driven into the notch 28 as is shown inwFig. 6.- This construction forms a'posipositionrelative' to the horizontal portion 5 and-willprevent itfrom either slipping up. i

seen that I have evolved acheap and simple tive lock for holding the end .22 in the same,

beater framework .which when assembled will never come-apart through use of the J beater, and willat all times be sorigid and fixed that the actuating means for the beater-T blades will always bein true alinement one with the other, and that the framework will .not be twisted and thereby clog the gears.
